AB SUMMARY: Lateral decubitus digital subtraction myelography is an effective technique for precisely localizing CSF-venous fistulas, a common cause of spontaneous intracranial hypotension. However, despite an optimal imaging technique, digital subtraction myelography fails to identify some CSF-venous fistulas for a variety of reasons. Here, we describe a technique involving conebeam CT performed during intrathecal contrast injection as an adjunct to digital subtraction myelography, allowing identification of some otherwise-missed CSF-venous fistulas.CBCTconebeam CTCTMCT myelographyCVFCSF-venous fistulaDSMdigital subtraction myelographyLDDSMlateral decubitus digital subtraction myelography
